Made mostly of collagen, bone is living, growing tissue. Think of bone as a bank account where you "deposit" and "withdraw" bone tissue. During childhood and the teenage years, new bone is added to the skeleton faster than old bone is removed. After age 20, bone "withdrawals" can begin to exceed "deposits." For many people, this bone loss can be prevented by continuing to get calcium, vitamin D, and exercise and by avoiding tobacco and excessive alcohol use. Osteoporosis develops when bone removal occurs too quickly or replacement occurs too slowly or both.
